Abstract

1,099,589. Charging heat treatment furnaces. ILLINOIS NATIONAL BANK & TRUST CO. July 5, 1966 [Aug. 18, 1965], No. 30184/66. Heading F4B. Apparatus for charging a continuous heat treatment furnace 12 comprises a hopper 34 with a sliding door 41 feeding a shoot 37 attached to a pair of shaker trays 30 with corrugated bores extending through the furnace, said shoot and trays being reciprocated by a pneumatic motor. The end of hopper 34 forms a preheating vestibule 15 with the adjacent end of the furnace casing 16, and door 41 is reciprocated at regular intervals by pneumatic motor 51 feeding workpieces on to the shoot 37. A wedge-shaped baffle 59 on the latter distributes said workpieces evenly on to trays 30. The door 41 slides in L-shaped ways 42 biased against a seal (49). Fig. 4 (not shown), between the bottom wall 39 of the hopper and the door. A neutral or inert atmosphere may be preserved in the furnace 12.
